Abstract

The invention relates to a dual-fuel automatic switching mechanism. The dual-fuel automatic switching mechanism comprises a carburetor assembly, an oil-gas switching assembly, a fuel gas pressure reducing valve and a connection pipe. A first connector, a gas inlet connector and a second connector are arranged on the fuel gas pressure reducing valve. One end of the oil-gas switching assembly is connected with the side face of the carburetor assembly, and the other end of the oil-gas switching assembly is connected with the first connector of the fuel gas pressure reducing valve. One end of theconnection pipe is connected with the second connector of the fuel gas pressure reducing valve, and the other end of the connection pipe is connected with a fuel gas inlet pipe of a carburetor. An oilhole is formed in the carburetor assembly. When fuel oil supply is switched to fuel gas supply, the oil-gas switching assembly blocks the oil hole from the side face of the carburetor assembly. Whenfuel gas supply is switched to fuel oil supply, the oil-gas switching assembly opens the oil hole from the side face of the carburetor assembly. The oil-gas switching assembly can tightly block the oil hole, instantaneous switching can be achieved, and safety is good.

Description

technical field [0001] The invention relates to the technical field of carburetors, in particular to a dual-fuel automatic switching mechanism. Background technique [0002] A carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum generated by the engine. In recent years, carburetors usually use dual-fuel engines. Dual-fuel engines are a new type of engine that can use gasoline fuel and liquefied petroleum gas fuel or natural gas as fuel. It has the characteristics of high efficiency and low pollution emission technology, and has a good development prospect. [0003] However, the engine dual-fuel automatic switching mechanism in the prior art is as follows: Chinese patent document CN201810357642.5, application date 20180420, the patent name is: dual-fuel automatic switching oil-gas dual-purpose carburetor and its bottom cup. Disclosed is a dual-fuel automatic switching oil-air carburetor and its bottom cup, including a carbur...
